And the most important question is, do you have the video of the crackling sound from your engine?

 

Does it sound like this?

 

If your 3 port is tuned like you said, how is it possible that the Dealer did not detect your ECU flashed your story doesn't match up at all. If your ECU checks ok that means You have NO TUNE in the ECU, and therefore over boosting to 30 PSI with your untuned 3port.

 

^ yes

 

Wonder what became of this issue?

 

Wait, did you retarded *** bring your car to the dealer not with with a Tune, with a 3 Port still installed?

And 2nd, YES the dealer has the ability to see when the Ecu HAS...HAS been tampered. My Dealer proved it to me but I could careless about Warranty as when I bought my car.... I knew warranty was gone when driving off the lot.

Point is, your not going to win this case let alone with your posts on here. Mitsu has peeople browse the forums to see technical issues like so to see if people are trying to scam out Mitsu for warranty.

A 3port is a good indicator you that you "do speed/race it" since when does ANYONE....ANYONE get an Intake, Exhaust, and a 3port as their first mods to not tune it pass 19-20 psi?



So your either troliing..... or just retarded. No Explaination needed.

 

That's the hard way to put it but yeah, it was def a bad idea to head over to the dealer with an untuned car and a boost controller installed....

 

sorry guys but i just bought a GrimmSpeed Electronic Boost Control Solenoid 3-Port for my evo 9 and intake and the exhaust. I am putting all the stuff in. You guys are saying that you dont recommednd to put GrimmSpeed Electronic Boost Control Solenoid 3-Port with the original ecu. explain me before i do all of this i am new in this vehicule.

You can use a 3port with the stock ecu, you have to tune it afterwards. It reacts much faster than the stock solenoid, and does not bleed boost like the stocker. If you throw it on with the stock wgdc, you will eventually grenade your motor.

 

100% correct, you are supposed to tune down the wgdc by roughly 30%, thats not speculation or suggestion that is straight from Grimmspeed.

 

Hey sorry to just Jump into this thread but I was wondering if anyone can help me I went to my local tuner and got a 3 port boost control soleniod it's their own brand and it came with a pic of how to install it fitting one gets boost pressure so I teed of my bov fitting 2 goes to wastegate so I used the hose that went to the waste gate from the oem solenoid and fitting 3 is vacuum so I put it to the factory intake return it plugs into the brown connector and im using a cobb ap with stage 3 but only getting 15 psi I also took out the boost pill going to the solenoid as per cobs instructions anyone have any idea

 

...wut ^

 

hello guys, I recently installed my 3port grimmspeed but I cant find the changes that I have to do in my ecu to tune it. Evodreamr says 3 post before this to tune down the wgdc by roughly 30%. Thats all? Is there any tutorial to do it? Dont have much tuners over here...

By the way I also installed a forge wastegate, and my boost has a peak on 28 and then goes to 20 at redline. Is it ok?

 

There is somewhat of a tutorial on youtube (search evo grimspeed 3 port). You'll need a laptop, tactrix cable, and a program like ecuflash to change the WGDC though.

 

Thank you ronaldo
